Can anyone tell me what that small radiator is behind the grill? I'm guessing it's either a transmission fluid cooler, engine oil cooler, or power steering fluid cooler. I'm thinking the latter because I took the lower cover off to get to the oil filter to try and follow the lines from that small cooler to the source. it looks like one of the hoses goes to the power steering fluid reservoir. If so, that seems kind of odd. I have an LE 4x4 with the standard tow package. Any guesses or answers?

If you are talking about the small cooler mounted in front of the radiator at the upper drivers side then it is the power steering fluid cooler. Most all vehicles have a power steering cooler of some type.
